Water Adsorption and Desorption of Upgraded Brown

2014-7-29  Isotherms of water adsorption and desorption of upgraded brown coal (UBC) were compared to those of its feedstock coals, dried and not dried. The shape of isotherms showed that UBC was exposed to an irreversible collapse of capillaries by losing its original water, as was dried feedstock coal. By analyzing isotherms from the viewpoint of heat of adsorption and heat of wetting, the affinity of

ANALYSIS OF UBC UTILIZATION IN THE EXISTING COAL

2020-7-30  Upgraded Brown Coal (UBC) Several upgrading techniques have been suc-cessfully developed around the world (Allardice and Young, 2001). UBC process that is devel-oped by Kobe Steel Ltd. of Japan is one of the most advanced solutions of upgrading, due to its relatively simple and mild process and also indi-cated by its lower pressure and

Ash deposition behavior of upgraded brown coal in

The UBC stands for Upgraded Brown Coal. The melting temperature of UBC ash is relatively lower than that of bituminous coal ashes. Combustion tests were conducted on blended coal consisting 20 wt.% of UBC and 80 wt.% of bituminous coal. Before actual ash deposition tests, the molten slag fractions in those coal ashes were estimated by means of
